MOTOR-VEHICLE.

SPECIFICATIQN forming` part of Letters Patent No. 683,977, dated October 8, 1901. Application tiled August 1, 1900 Serial No. 25,575. (No modelo' To all whom, it may concern:

Be it known that I, ALEXANDER PA-LMRos, a citizen of Finland, residing at Columbus,

in the countyof Franklin and State of 0hio,

have invented certain new and useful Improvements in Motor-Vehicles; of which the 'following is a specication, reference being had therein to the accompanying drawings.

This invention relates to improvements in vof a propelling or motor vehicle embodying my invention. Fig. 2 is a planview of the same, parts of the running-gear of a carriage or similar vehicle being shown as connected therewith. Fig. 3 is a front view of the parts shown in Fig. Figs. i and 5 are side elev-ations on a smaller scale, showing the propelling-vehicle connected with vehicles to be propelled. Fig. 6 is a horizontal section showing a part of the driving mechanism. Fig. 7 is a vertical transverse section showing a detailof the steering mechanism.

In the drawings I have shown parts of the body and running-gear of van ordinary vehicle, for it will be understood that 'the invention is embodied in a mechanism of such sort that it can be readily applied to a carriage, buggy, wagon, or similar vehicle of the ordinary sorts, one of the purposes being to prbvide a propelling device which can be readily and quickly applied to such vehicle without requiring any alteration or modification thereof.

A A indicate the rear wheelsof such a vehicle, and A A the front wheels. rI he rear wheels. are mounted on the axle B and the front wheels on the axle B', which, together with the other parts of the .running-gear, can be of any usual or approved form. To these parts'can be connected the motor or the motor-vehicle, for in the present construction the parts which `Meattached consist of'a can* riage or truck frame carrying the'` motor `Yproper and the means for generating the power to actuate it. lThese may comprise an oil-engine and a tank for the oil or an eleotric motor and a battery for energizing; For sake of illustration I will herein consider that an electric motor and battery are used.

E E are two rear wheels upon an axle F, 'and E is a front wheel uponan axle F,and these mediately or immediately support the truck-,frame of the motor and the parts connected therewith.

D indicates the bod of the motor-carriage,-

which in this vcase is a boxor chamber-'containing the storage battery, and 'at D'j there isan extension of the framev or box, inl which is mounted the motorvD'i. The latter is geared tothe axle F of the driver, preferably by means of a compensating gearing, indicated as a whole by D3, one part 'thereof being connected to the right-handdrive-wheel E and the other part being connected to the lefthand wheel. The inode of action of these parts is well known, they insu-ring that the power can be uniformlyapplied to the two ground driving-wheels irrespective ofthe speeds at which they travel, their speeds of rotation varying as the vehicle turns to the right or the left from the normal central line longitudinally.

Preferably -the frame or boxing ot the driving mechanism is recessed on'theu'nder side, as shown at d, to provide a' free space for the axle F, and the connection between the latter and the frame 'and box is such as to permit the latter to rise and fall, this con-. nection consisting of springs j and `springcarrying bars f'. The motor is hinged to thev .axle at one side or end, and at its opposite.

standards, which are connected to the axles B and B in such va way that there shall be a limited amount of Vvertical play of thc frame with respect to the axle and yet have the joined parts held in proper relations to cach other laterally. This can be accom plishcd in IOO any suitable way. I have illustrated one method which can bev followed. As-shown, the motoreframe at the rear end has the standards II and the extension parts H', which are connected to the standards by thel bolts h, there being vertical longitudinal slots at h to permit the part H' to be adjusted vertically, so that the apparatus can beapplied to vehicles with axles relatively low or to others with their axles at a higher line. 4, The upper part H' is slotted at its upper end, as shown at 72.5. The upper end of the opening is closed by a bar or plate 71.2. To hold the axle snugly in position, an adjustable plate, as at h3, can be employed with adjusting and fastening devices, such as the bolts h4. At the front end the frame has standards I with upwardly-y projecting extensions I', adjustably secured to the standards by the bolts 'L' in the slots i', and the extension having the slots i5 for the axle B', the retaining-bar 2, and the adjusting devices 'i3 it. The front standards I, however, are not rigidly connected with the frame, but are joined by means of a cross plate or frame K, which carries the yoke J, that supports the front wheelE'. This wheel, its yoke J, the standards I, the front axle B', and the front wheels A' can all be turned or adjusted horizontally independently of the motorframe to permit the steering of the vehicle. Such loose connection is shown as being provided by means of the frame-piece L, which has a bearing that receives a journal carried by the front swinging frame. This part L rests upon the yoke .Iof the front wheel, and thus provides support for the front end of the motor frame. Preferably the motorframe extends .to the front of and around the front wheel E', there being a passage-way or aperture F2 in the motor frame or box, in which are situated the wheel E' and its yoke .I and which permits the wheel to be turned to the right or the left relatively to the motorframe. l v

It will now be seen that the propelling mechanism can be readily and quickly applied to a vehicle, as it is merely necessary to place the truck beneath the running-gear of the carriage, and the clip-pieces Il' and I' being moved or opened suiiiciently to bring the axles B and B' into'their proper positions over the parts below the attachment is effected by swinging the parts H' and I up until they inclose the axle and then clamping them properly to the parts II and I and securing the retaining-bars H2 and I2.

By means of collars or clips, as shown at IJ P, secured to the axles the standards andextensions are prevented from'moving laterally,

although free to accommodate thelnselves vertically. I

By having adjusting devices, such as those at h3 and h4 and at .t3 and i4, or equivalent mechanism provision is made for meeting variations in the distances between the axles B and B', and the same motor can be applied zo avehiclc having its axles relatively closer together and to another vehicle having its axles relatively farther apart.

The motor frame or box is also provided with the devices for steering, mechanism for operatin g the controller, and means for working the brake. preferred way. As shown, there are three shafts' M, N, and Q,l preferably concentric with each other. They are mounted in alat` erally-projecting standard or'frame carried by the motor-frame, as shown at R, and are so situated as not to be interfered with by the floor or other parts of the vehicle and so that the handles or levers at M', N', and Q' shall be accessible to one-in the drivers seat,

The shaft M is connected by a crank m, -a link m', and a crank m2 to the above-described frame I J K, secured to the front axle, and the operator can by means of lever M cause these parts to turn the axle and the front" These can be applied in any Wheels A A' tothe right or to the left for steering;

The shaft N is connected by the devices at S With the controller S', which in the details of its construction may be of any of the now Well-known sorts. l

The shaft Q is connected bythe mechanism at T with the brake. I

Having above described the several parts which constitute al mechanism embodying my improvements and the manner of attaching the motor-vehicle to the vcarriage and of disconnecting it therefrom, it will be unnecessary to describe the manner of operating it, as that will be fully understood from the above description and drawings.
